Read the first 7 Welding Safety & OSHA Regulations flashcards as text

  1. Under OSHA 29 CFR 1910.252, what is the minimum safe distance from combustible materials when performing hot work if materials cannot be moved?

    Answer: 50 feet

    OSHA 29 CFR 1910.252 requires combustibles to be moved at least 35 feet from hot work, or protected with fire-resistant shields.

  2. Which OSHA standard specifically governs welding, cutting, and brazing in general industry?

    Answer: 29 CFR 1910.252

    OSHA 29 CFR 1910.252 is the primary standard covering welding, cutting, and brazing operations in general industry.

  3. A welder develops a persistent cough and shortness of breath after months of working with galvanized steel without proper ventilation. This condition is most likely:

    Answer: Pneumoconiosis

    Prolonged inhalation of welding fumes without adequate ventilation can cause pneumoconiosis, a chronic lung disease from accumulated particulate matter.

  4. When using an arc welding process in a confined space, which hazard requires the MOST immediate attention before entry?

    Answer: Oxygen-deficient or enriched atmosphere

    An oxygen-deficient atmosphere (below 19.5%) or oxygen-enriched atmosphere (above 23.5%) is immediately dangerous to life in a confined space.

  5. What does the acronym 'IDLH' stand for in the context of welding fume exposure limits?

    Answer: Immediately Dangerous to Life or Health

    IDLH stands for Immediately Dangerous to Life or Health, representing the maximum concentration from which a worker could escape without irreversible health effects.

  6. Which type of fire extinguisher is classified as appropriate for fires involving energized electrical equipment in a welding area?

    Answer: Class C

    Class C extinguishers use non-conductive agents suitable for fires involving energized electrical equipment without risk of electrocution.

  7. An employer is required to maintain MSDSs (now called SDSs under HazCom 2012) for welding consumables. How long must these records be retained according to OSHA?

    Answer: 30 years for potential carcinogens

    OSHA's hazard communication and exposure records standard requires retention of employee exposure records, including SDSs for carcinogenic substances, for 30 years.
